(Up to IPP Progress Reports)

Eugene Magnier

Heather Flewelling

• copied my home files from 004backup to either 053home or to a good place for data
• restarted replication pantasks on ipp user
• investigated MD09.20090904 processing from last week
• burntooled MD09 and MD10 dates
• found instances where burntool burns files out of order
• while burntooling (and with lots of NFS glitches) pushed the load on 041 to 130. YIKES.
• found corrupted raw image file
  • copied both copies (the corrupted and the uncorrupted) to a safe place, neb-culled the corrupted file, neb-replicated the good file
• processed MD09 through to warp stage
• started MD09 stacking
• added processing status to wiki

Bill Giebink

This week I finished locating and making notes on code causing seg faults and aborts from the psLib tap tests. I started fixing tests and hopefully my work will still be there when ipp000 comes back up.

I also spent some time looking for some cards for Jim Heasley at MHPCC, but didn't find what he wanted. And I started working with Heather to script the characterization of the reduction process.

Paul Price

• Detection efficiency: branches/pap
  • Measure magnitude bias from fake sources
  • Discovered bug in statistics on fake source magnitudes:

psphotFitLinear and psphotMagnitudes sort the source list)

• Fixed radius of fake sources (pmReadoutFake)
• I/O through FITS table in CMF file (chipname.deteff)
• Optimised through convolving only the pixels of interest
• Contributes 1.4 sec of 66 sec psphot run time (on 6k square warp,

unthreaded, optimised on ipp022)

• Ready to merge into trunk

• MOPS support
  • Compiled Magic for Jan Kleyna to test comets
  • Magic does not compile with recent gcc (4.3.2 doesn't work; 4.1.2

does); mentioned this to Paul Sydney previously, but no response yet

• Processing
  • Discovered that MD09.20090904 was done without PATTERN turned on
• Stack/Diff convolutions
  • Assisting Draper/Metcalfe (stack) and MWV/Huber (diff)

investigations

• Wrote up stamp selection algorithm for ps-ipp-users
• Fixed ppStack so that extended sources can't be used as stamps for

PSF matching

Bill Sweeney

Bill spent the week preparing the postage stamp server for general availability.

• created a web page to allow users to upload a postage stamp request table for testing
• modified the request form page to use a session to make it more user friendly
• added user authentication to the pstamp site
• fixed various bugs uncovered in testing
• wrote some wiki pages for describing how to create requests files
• lots of testing
• started updating instructions on installing the ipp data store software

Chris Waters

• tracked down spurious supernova transients for Armin Rest, and determined that they were not burntool related.
• merged my svn branch to the trunk, adding the cleanup, addstar stage, and burntool tools.
• fixed all known bugs arising from that merge.
• worked with John Tonry on implementing different noise thresholds for burntool. Have not determined that the current value of 20 isn't already good enough.
• attempted to implement a burntool_state variable in the register stage.
• gave a talk.
